TECHNICAL FIELD

The present utility model refers to a type of fitness equipment, inparticular to a type of dual function fitness equipment.

PRIOR ART

In the field of fitness equipment, stationary bikes are widely used dueto their simple and easy to use structure. The existing stationary bikesare divided into vertical and with back support, among others. However,they usually have a sole function, that is, that the user sits in theseat, with his hands on the handlebars and his/her feet in the pedals,simulating the movement of riding a bicycle with a sole function or withsome additional functions. For example, some stationary bikes haveadditional handles that may help to exercise the arms. However, theirdefect is the sameness of the basic frame of the stationary bike and thepossibility of adding a few additional functions, without modifying thegeneral function. Therefore, it is impossible to satisfy more needs.
